The mechanism of the protective action of ABA was investigated, suggesting a conjugated interaction with lipid-transporting proteins (LTP) and their participation in the formation of lamellae of suberin in pea roots during salination. The immunohistochemical method showed that the NaCl-induced accumulation of LTP and ABA in the cell walls of the phloem was accompanied by the deposition of suberin in the endodermal region of the roots of pea seedlings. Unlike LTP, which were localized around phloem cells, ABA was present inside these cells. In addition, treatment of control plants with exogenous ABA led to the accumulation of LTP in phloem cells and contributed to root corking. Analysis of phloem exudate for the presence of LTP revealed an increase in their content under salinization conditions. These results indicate the importance of NaCl-induced accumulation of ABA in the regulation of LTP levels and enhanced formation of apoplastic barriers in the roots of pea plants.</p></abstract><trans-abstract xml:lang="ru"><p>Известно, что реакции растений на стрессы координируются множеством регуляторных сетей, включая индукцию эндогенной абсцизовой кислоты (АБК). Исследовали механизм защитного действия АБК, предполагающий сопряженное взаимодействие с липид-транспортирующими белками (ЛТБ) и их участие в процессах формирования ламелл суберина в корнях гороха при засолении. Иммуно-гистохимическим методом было показано, что NaCl-индуцированное накопление ЛТБ и AБК в клеточных стенках флоэмы сопровождалось отложением суберина в эндодермальной области корней проростков гороха. В отличие от ЛТБ, которые были локализованы вокруг клеток флоэмы, AБК присутствовала внутри этих клеток. Кроме того, обработка контрольных растений экзогенной АБК приводила к накоплению ЛТБ в клетках флоэмы и способствовала опробковению корней. Анализ флоэмного экссудата на присутствие ЛТБ выявил увеличение их содержания в условиях засоления. Эти результаты свидетельствуют о важности NaCl-индуцированного накопления AБК в регуляции уровня ЛТБ и усиленного образования апопластных барьеров в корнях растений гороха.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Pisum sativum L.</kwd><kwd>NaCl-salinity</kwd><kwd>lipid-transporting proteins (LTP)</kwd><kwd>abscisic acid (ABA)</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Pisum sativum L.</kwd><kwd>NaCl-засоление</kwd><kwd>липид-транспортирующие белки (ЛТБ)</kwd><kwd>абсцизовая кислота (AБК)</kwd><kwd>суберин</kwd><kwd>апопластные барьеры</kwd><kwd>иммунолокализация</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке темы № 123020800002-2 в рамках государственного задания Министерства науки и высшего образования РФ № 075-01134-23-00.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Hoh F., Pons J.L., Gautier M.F., de Lamotte F., Dumas C.
